Zachariae-79N

The Thule OIB team completed the high-priority land ice mission Zachariae-79N today. The NASA GV encountered some clouds for about 200 nm west of the Greenland ridge, and flew into clear conditions on the north east region of Greenland. OIB remote sensing instruments on the GV worked well today, (with a minor disk issue for ATMT7 narrow scan green causing a small data gap on the return to Thule), and some clouds encountered on the return.

Today ICESat2 overpass (IS-2 RGT 1053) occurred at 0052Z this morning for a latency of 13 hours.

For the second day in a row, NASA had 3 aircraft conducting research over Greenland. The AVIRIS instrument flew on the B200 primarily focusing on the OIB’s northern return track across the Greenland ice sheet, and the OMG Basler BT67 flew a mission along the northwest coast of Greenland.
